Surprise move sees Tony Douglas take up post of chief operating officer at Terminal 5 builder
Douglas will be replaced by Heathrow managing director Mark Bullock at the end of the month according to a BAA statement.
Douglas was the managing director of the Terminal 5 construction project before being appointed airport managing director in March last year. In July 2006 he was appointed chief executive officer of Heathrow.
BAA Chief Executive Officer Stephen Nelson said: "Tony's outstanding achievement for BAA had been the development of Terminal 5, one of Europe's largest building projects, which remains on time and on budget."
